A Case study for opportunities of a river: The river Nile
Water supply: Water is used for washing, cleaning and drinking for people close to the river. 96 percent of Egypt is unpopulated as almost all people live near the river Nile.
Transportation: Many railways and roads use the vally to travel North - South and also a suger cane factory at Armant transports sugar cane across the river.
Agriculture: Farmers grow fodder crops for cattle as well as foods such as bananas and peanuts in the flood plain.
Tourism: Local people gain employment on the cruise ships or by providing services to the tourists on shore. Cruising gives an opportunity for tourists to enjoy the view as well as stop at historical sites.
Hydroelectric power: The High Aswan Dam holds back the worlds 3rd largest man made lake. This dam produces half of Egypts electricity.
A case study for what has been done to reduce the risk of flooding at a river: The river Elbe
​Between the 39th of May and the 2nd of June 2013 the was a major flood in Germany/Czech Republic due to the river Elbe

Impacts of the flood	Responses/Management
At prague, half the metro stations closed, trained to Berlin weer diverted, chemical factories were closed, 50000 people were evacuated and tigers at Prague zoo were tranquilised and moved.	Protective metal barriers have now been strengthened and more mobile metal barriers are now available. Residents hare are used to using sandbags.
At Dresden, the city was flooded, bridges were closed to traffic, thousands of residents put up sandbags and flood barriers	Water was pumped back into the river. Now there are higher levees, stronger walls and flood barriers. Part of an old estate has been sacrificed to allow the river to flood there in future.
At Magdeburg, the levees were not built very strong. 23000 residents were asked to leave their homes because a dam burst. 19000 soldiers were sent to help.	Helicopters were used to airlift stranded residents. Levees are being moved back to allow more space for the rover to flood. Unfortunately, as Prague and Dresden improve their defences, Magdeburg recieves even more water.
Hamburg suffered little damage due to warnings and an established flood protection scheme.	There are protective walls and levees that are 100km long.Sirens and warnings can be issued because Hamburg is far from the source.
